Hey Mark,
I think I did sell you some a few years ago. Did you get that really small one from me? I called it "PeeWee"...does that ring a bell? My friend that went to Thailand just wrote me and said there were none to be found in places that traditionally had big-heads available. The locals basically said forget about it. Kind of sad that at least that one area has been hunted dry.
